Error running development server with Postgres user in Django

Question

Switching from user "postgres", I created a new Postgres user and changed my Django project to make use of this new user / credentials:

sudo -u postgres -i
psql -c "CREATE USER foo WITH PASSWORD 'xxxxxxxxxxxx' CREATEDB;"
psql -c "GRANT ALL PRIVILEGES ON DATABASE bar TO foo;"

In settings for Django:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'bar',
        'USER': 'foo',
        'PASSWORD': 'xxxxxxxxxxxx',
        'HOST': 'localhost',
        'ATOMIC_REQUESTS': True
    }
}

But I get the error when using "python manage.py runserver":

django.db.utils.ProgrammingError: permission denied for relation django_migrations
